E1M1 (BOBKDV2)

E1M1 is the first map of BOBKDV2. It was designed by Bob Carter. It was later adapted into E2M7 of The Lost Episodes of Doom.

Secrets

 * 1) The exit room counts as a secret and is impossible to miss. (sector 61)
 * 2) There is a switch behind a barrel in the northern part of the level.  This opens a door in the start room (access to which requires the red key which can be found in a room accessed by a secret door in the west wall of the alcove near the lift in the north of the level), which leads to a nukage area.   (sector 69)
 * 3) Upon entering the south-easternmost room from the east, a door opens in the north wall leading to an area with a radiation shielding suit and a partial invisibility.  The door closes after a few seconds, but can be re-opened as often as needed. (sector 79)
 * 4) The area accessed by #2 can be exited by a staircase, which has a secret sector at its base, leading to a ledge from which a BFG9000 can be obtained. (sector 93)
 * 5) Jumping into the large nukage pool, there is a soul sphere on a platform which can be lowered, allowing access to a ledge.  Walk to the end of this ledge – there is a secret door leading to an area with several soul spheres, megaarmor vests, and energy cell packs. (sector 104)

Bugs
The red key, which is required to reach secret #2 and secret #4, is not present on easy skill. As a result, on easy skill the maximum achievable secret percentage is 60% and the maximum achievable items percentage is 86% (there are two partial invisibilities and a soul sphere in the nukage area).
